Resolved Caveats—Cisco IOS Release 12.0(28)S3
Workaround: There is no workaround.
• CSCsa46699
Symptoms: A Cisco 7200 series may crash because of a bus error when you remove a subinterface
or when you remove a service policy from an interface.
Conditions: This symptom is observed when a hierarchical policy map is configured, when the
policy map has a police action in the child only, and when the policy map is attached to two
interfaces. When the service policy is removed from one of the interfaces, the router may crash.
Workaround: Configure the same policy map with a different name on each interface.
• CSCsa46859
Symptoms: Cisco 10000 series routers using ATM VC bundles and QoS may have packets dropped
when an external ATM VC bundle using DSCP type of service traverses the Cisco 10000.
Conditions: When using ATM VC bundles and Cisco IOS Release 12.0 S on a Cisco 10000 series
router, ATM VC bundle traffic may be dropped. The problem arises when ATM bundles using DSCP
enter the Cisco 10000 router which only supports MPLS EXP type of service bits. Those code points
not matching an MPLS EXP TOS value exactly are dropped.
Workaround: Either use MPLS EXP for ATM bundles leading into the Cisco 10000 router or only
use DSCP values that map to the MPLS EXP values.
• CSCsa46887
Symptoms: A router builds an Echo Reply that is invalid and may be misunderstood.
Conditions: This symptom is observed on a router that is configured for LSPV when the router
receives an Echo Request with a Pad TLV that has a value of “Copy Pad TLV to reply.” The Echo
Reply that the router builds includes residual data from previously received packets instead of the
pad pattern that was received.
Workaround: There is no workaround.
• CSCsa47020
Symptoms: When Multilink Frame Relay (FRF.16) is configured on two bundled serial links and
when the traffic rate is above 2 Mbps, packet loss occurs.
Conditions: This symptom is observed on a Cisco Catalyst 6500 series and a Cisco 7500 series when
you send a 64-byte Ethernet frame. The symptom does not occur when the frame size is 512 bytes
or more.
Workaround: There is no workaround.
• CSCsa49740
Symptoms: Packets are punted to the GRP at a rate of 5000 pps, causing the CPU utilization of the
CPU to reach more than 50 percent.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(26)S3 when a 4-port Packet-over-SONET OC-48c Engine 4 plus line card
(4OC48E/POS-SR-SC=) receives TCP packets with destination 0.0.0.0.
Workaround: There is no workaround.
• CSCsa53001
Symptoms: A VIP6-80 in which a PA-MC-STM-1SMI is installed crashes.
Conditions: This symptom is observed on a Cisco 7500 series that runs a Cisco IOS interim release
for Release 12.0(31)S after link flaps occur on the PA-MC-STM-1SMI that has QoS configured its
serial interfaces.
